SPECIFICATION forming part of Letters Patent No. 638,975, dated December12, 1899.

Application inea August 2, 189s.

To all whom, it may concern:

Be it known that we, CHARLES MILLs, ot' Newton Upper Falls, and LORENWV. PENNEY, of Newton Highlands, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inDrawing-Frames, of which the following is a descriptionsuflicientlyfull, clear, and exact to enable those skilled in the art to which itappert-ains or with whichit is most nearly connected to make and use thesame.

This invent-ion has relation to that class of machinery employed in thepreparation of textile bers for the operation of spinning, commonlyknown as drawingrames or drawing-machines, employed chiedy for thepurpose of improving the parallelizing of the tlbersand the equalizationof the weight and thickness of the slivers treated thereby.

It is the object of the invention to so improve an organizeddrawing-frame as that the principal purposesthereof may be carried outmore efficiently, economically, and conveniently than heretofore.

In the disclosure of the invention as will hereinafter appear adescription will be given of the structural character of theimprovements created and the mode of their operation will also be setforth, and in connection therewith, where it isnecessary, the advantagesgained and mischiefs or objections overcome will also be stated.

Reference is to be had to the annexed drawings, and to the lettersmarked thereon, forming a part of this speciiication, the same lettersdesignating the same parts or features, as the case may be, whereverthey occur.

Of the drawings, Figure lis a plan view',partially in section, of somuch of a drawingmachine as it is necessary for the purposes of thisspeciication to show, the said drawingmachine being equipped with ourimprovements. Fig. 2 is a plan view of a portion of the rear roller ofthe pair of delivery-rollers detached, showing our improvements so faras they are -connected therewith. Fig. 3 is a vertical cross-sectionalview taken through the upper part of a drawing-machine provided with ourimprovements. Fig. et is a partially-sectional view of a trumpet and itsadjuncts and some of its copcrating parts,

Serial No. 687,532. (No model.)

as will more fully appear hereinafter. Fig.

p 5 is a diagrammatic View, in side elevation, of

a stand for supporting the gearing for operating the rollersV of theseveral heads in a drawing-machine. Fig. 6 is a plan view of the standand most of the gearing, as well as the pulleys for operating thegearing. Fig. 7 is a plan View, on enlarged scale, of one of the coilermechanisms, together with atrurnpet and appurtenances. Fig. 8 is asectional detail view of a coiler-tube gear, its drivinggear, and someof the associated parts.

In the drawings, @designates the fixed supporting means of the machine,which may be called the frame b designates the drawing-rolls, arrangedin sections or deliveries and receiving the material to be operated uponfrom the feedrollers c, back of which is theguide-plate cl.

The parts so far described form no part of our present invention, andtherefore may be of the form shown or any other suitell'to the purposefor which they are used.

Ve designates the front calender-roller, one being required for eachsection or delivery, the journals of which rollers are loose in theirbearings, as usual, so as to afford play to the rollers in directions toand from the rear driving calender-roller f, which is made in one pieceextending the length of the frame. We make the rear calendering-roller fsmaller in diameter than the front rollers and arrange the pair ofrollers so as that the lowest lines of their peripheries shall be uponsubstantially the same horizontal plane in order that when viewed fromabove the rear roller will appear to be and to all intents and purposeswill be lower than the front roller. This construction, for one thing,enables us to cant the trumpet h in'such manner that the sliver passingfrom the drawing-rollers to the cal-V ender-rollers may extend upon amore, nearly direct line than though the trumpet were held in levelposition, the latter arrangement resulting in advantages obvious tothose skilled in the art, chief among which is the vertical delivery ofthe slivers into the tube of the coiler-gear.

Where two calender-rollers of the same size are arranged with their axesin the same horizontal plane, the sliver coming from the loo , downward.

drawing-rollers is required to make too sharp a bend into the trumpet,which with this arrangement of calender rollers necessarily standsvertically over the bight between the latter. On the other hand, if thecalenderrollers are arranged obliquely to allow a disposition of thetrumpet which will avoid the abrupt bend of the sliver, the latter willbe shot forward instead of delivered directly To overcome the abovementioned difficult-ies, it has been customary to employ three rollers,the two calender-rollers set obliquely and the third being aguidingroller to direct the sliver straight downward into thecoiler-tube. By our arrangement above described the extra roller isdispensed with, while all the advantages of the threeroller arrangementare retained. As above stated, the reduction in diameter of the rearcalender-roller, while its lowest peripheral line is kept in ahorizontal plane embracing the lowest peripheral line of the largerfront roller, provides for sufficient canting of the trumpet to avoidtoo sharp a bend of the sliver. Again, although the axes of the ltworollers and the line of contact between them are in an oblique plane,yet the sliver will be delivered directly downward, owing to the factthat the large front roller is longer in contact therewith than is thesmall rear roller, it being borne in mind, in this connection, that thesliver expands immediately after passing the line of contact between therollers.

We construct the driving calender-rollerf preferably of one solid pieceof steel, turning down the same at intervals to form bearingnecks andcut gear-teeth z on the end of each section,-as shown, which gear-teetht engage the teeth of the gears j, secured on the ends of the frontrollers. The gear-teeth i are shortened to their pitch-line relativelyto the teeth of the gears j with which they mesh. Under this improvementthe front roller is disengaged from the driving means of the rear rollerand delivery is stopped before a com paratively great amount of fiberbecomes wound thereon and before delivery would be stopped under theconstruction in common use. This is a matter of much importance, sinceif the machine is not stopped quickly after the fiber commences to windon the rollers serious mischief results. Again, it is more advanta geousand economical to eut the teeth upon the roller f, as we do, than tomake the gear in halves and pin said halves on the roller, as wasnecessary heretofore with the inner gears, since they could not beslipped 'on from the end of the roller, and in addition to this thegears t, as we form them, are more durable than those heretofore formed,since it is obvious that if the teeth were long or of full length theywould be more likely to be broken by reason of their subjection togreater strain. Moreover, by making the rear rollersmaller, as we do,and cutting the teeth t' thereon, as described, more space is left atthe end of the roller for the employment of a greater ran gcofchange-gearing forpreservingthe right tension upon the sliver.

k designates the main gear-stand, which is provided with a anged base Z,whereby provision is made for bolting or otherwise securing it to thetop of the roller-beam in, so that,

when once secured in place it becomes to all intents and purposes onewith the beam. The main gear-stand above its base may be made of a Hatpiece of metal, milled on both of its sides and on its foot, so that itis easy and economical to make and finish, besides being otherwiseadvantageous, as will presently appear.

The main or leading feature of our improved main gear-stand is that itis so constructed as to adapt it to carry all of the end bearings andgearing necessary for driving all of the rolls and the frontcoilershaft, whereas under former constructions of this kind it required twoor three separate stands to accomplish the same purpose, which formerstands had to be removed or separately adjusted when any roll or gearwas taken off or adjusted.

The sta-nd is provided with a curved slot n in form concentric with theaxis of the shaft 0, having affixed upon it the driving-gearp, one endof the slot a being enlarged, as at q. By this means'when it isnecessary to change the speed of the calender or finishing rollers thenut for securing the journal-stud of the change-gears r in place may beloosened, the said stud moved up to the enlarged point q of the slot,the stud and gear removed, another gear or gears substituted, and theparts returned to and secured in place without disturbing the stand, andthe work can readily be doneby one person. The form ot' t-he slot nprovides for keeping the gear s2 in proper mesh with the driving-gear pand also for adjusting the gear r (which is fastened on the hub of thegear s2) into requisite mesh with the coiler-shaft gears on the end ofthe coiler-shaft d@ which gear s isa change-gear for varying speed tosuit different sizes of coiler-cams.

The calender-rollers, itwill be understood, are driven from thechange-gear r (which is practically compounded with the gear s2) throughthe medium of the coiler-shaft gear s and the idler s meshing withthegear on the back calender-roller. The gears s s for the sake ofclearness are omitted from Fig. 6.

The draft-gear u, which is also a changegear, has its journal-studsupported in a bracket e, which is adjustable on the maingear stand bymeans of a bolt w, which may move in a slot formed in the bracket, whichslot is curved in form concentric with the driving-shaft, as shown. Thebracket u is on the driving-shaft, so that it can be swungconcentrically thereabout, keeping the crowngear y (with which thedraft-gear n is compounded) in proper mesh with the drivingwheel andalso allowing the draft-gear u to be brought into proper mesh with thegear which it drives.

The removable and change gearing are arranged, as is necessary to apractical and economical construction, on the same side of the stand asthat from which the rollers eX- tend. This improvement is important,since, as before shown, itv is economical and efficient, permits thework to be done by one person without removing the stand, and allows anygear to be taken out without removing the others.

.e a" designate fast and loose pulleys, from which the machine isoperated and by which it is governed.

a designates the front half of the cover for the coiler-tnbe gear b,thesupport b" for which cover and gear extends out over the coilercan c andis rabbeted at c to accommodate the lower edge of the front half ot thecover. The front half of the said cover is made removable, While theback half Uf'is stationary. This construction enables us to readilyremove the front half a of the cover by simply lifting it off andplacing it to one side around the adjacent cover, as is shown in Fig. l,(a portion of the front calendering-roller being represented as brokenaway to better show the construction,) in order to get in to correctanything in connection with the coilertube gear or to remove the latteror any of its connections. The back part of the cover connects withadjacent covers, all of the joints being close andthe upper surfacessmooth, so that neither dust nor lint can get below the covers and sothat the surfaces can easily be cleaned by dusting or brushing.Heretofore in case the sliver passing through the coiler-tube gearshould bung up or in case of other similar mishap it was necessary toremove the entire cover and generally the gear also to set things right.

d designates the coller driving-shaft, arranged below the covers a andprovided at each head with a small bevel-gear e', which meshes with alike bevel-gear f', setinto and connected with the hub gf, Fig. 8, of agear 7;', which meshes with and drives the coilertube gear h'. The hubsof the gears f' and 7L turn on a stud t', set into the frame-plate, andthe latter is countersunk to provide a bearing for the rimj of the hubg', so that the said countersink may be freely supplied with a lubricantand the overflow therefrom may iiow over to the recess formed in theplate for the rim-bearing 7c of the coiler-tube gear.

By the construction just described the parts are brought close togetherverticallyin order that they may be made compact, be easily lubricated,and otherwise made eiiicient vand ready of access.

The pivoted arm l of the trumpet is provided on its under side with anadjustingscrew m', Fig. 4, which supports the trumpet in position byresting upon a pivoted lever n', the latter in turn resting upon thecoiler-gear or its cover, so that as the coiler-can becomes filled andraises the coiler-gear the trumpet willbe raised and the machine will bestopped.

The usual stopping mechanism is shown in Fig. 3, on which the arm of thetrumpet acts through the medium of the usual con'trivances to stop themachine.

In Fig. l we have-shown the front half of the cover to one coiler-gearas removed and placed around and over the front part of the coiler-gearnext to the right. This gives opportunity for free access to thecoiler-gear and its adjuncts in an easy and convenient way.

Vte may repeat that we regard the single main gear-stand as a veryimportant part of our invention, since in addition to what has alreadybeen said of it it leaves room for a greater range or extent ofchange-,gearing and allows of the same being easily and quickly adjustedand secured in place.

Having thus explained the nature of the invention and described a wayofconstructing and using the same, though without attempting to set forthall of the forms in which it may be made or all of the modes of its use,it is declared that what is claimed is- 1. In a drawing-machine, t-hecombination with an obliquely-set trumpet; of front and rearcalender-rollers, the rear one being appreciably smaller than the frontone and the lowest peripheral lines of the two rollers being insubstantially the same horizontal plane.
